Medium - grade magnesia is widely used

Middle-grade magnesia in used in metallurgy, smelting, senior magnesite brick, refractory and moisturizing materials manufacturing, also widely used in rubber, rubber sheet, rubber products, medicine industry, food industry, plastic plate promoter, glass fiber reinforced plastic plasticizer and silicon steel sheet surface coating of paint, paper production of filling material and reinforcing agent, steel ball polishing agent, leather treatment agent, insulation materials, oil, dye, ceramic, desiccant, resin, flame retardant used for rubber and plastic products of the filling material and strengthening agent, soft magnetic ferrite, adhesives, chemical industry as catalyst and make other magnesium compounds, enamel, ceramics, glass and other materials.

Excellent flame retardant and filler for plastics, rubber and other polymer materials, as desulfurizer for flue gas in environmental protection, can replace caustic soda and lime as neutralizer for acid wastewater; Used as an oil additive to prevent corrosion and desulfurize; Used for refining of electronic industry, medicine and sugar; Used for insulation materials and manufacturing other magnesium salt products; Fused magnesium is one of the important raw materials of refractories, used in the manufacture of various magnesia bricks, magnesia aluminum bricks, ramming materials, charging materials and so on. Containing more impurities, used for paving the bottom of the steel furnace.

Magnesia is a kind of refractory.It takes magnesium oxide (magnesia) as the basic aggregate, mixes it with magnesium chloride solution, adds a small amount of talc, quartz sand, glass wire, knots forming, the refractorycan reach 400 degrees Celsius, high energy up to 1700 degrees. Heavy - fired magnesium, good sintering degree, uniform chemical composition, stable quality. Mainly used for steelmaking open hearth furnace, electric furnace sintering furnace bottom and ramming lining.

Refractoriness refers to the Celsius temperature at which a conical specimen of a refractory material withstands high temperature without softening the molten material under load. Refractory materials appeared with high temperature technology, which originated in the middle of the Bronze Age. In the Eastern Han Dynasty, clayey refractory materials were used as kiln materials and saggers for firing porcelain. The refractories are developing towards high purity, high density and ultra-high temperature products. Meanwhile, amorphous refractories and refractory fibers with low energy consumption and no burning are emerging. Modern, with the development of atomic energy technology, space technology, new energy technology, with high temperature resistance, corrosion resistance, thermal shock resistance, erosion resistance and other comprehensive excellent properties of refractory have been applied.
